Definitions

  • This invention relates generally to the field of geophysical prospecting. More particularly, the invention relates to the field of marine sensor cables for marine geophysical surveys.
  • geophysical prospecting is commonly used to aid in the search for and evaluation of subterranean formations.
  • Geophysical prospecting techniques yield knowledge of the subsurface structure of the earth, which is useful for finding and extracting valuable mineral resources, particularly hydrocarbon deposits such as oil and natural gas.
  • a well-known technique of geophysical prospecting is a seismic survey.
  • Marine geophysical surveying such as seismic surveying
  • sensor cables such as “streamers” towed near the surface of a body of water or an “ocean bottom cable” disposed on the water bottom.
  • a streamer is in the most general sense a cable towed by a vessel.
  • the sensor cable has a plurality of sensors disposed thereon at spaced apart locations along the length of the cable.
  • the sensors are typically hydrophones, but can also be any type of sensor that is responsive to the pressure in the water, or in changes therein with respect to time or may be any type of particle motion sensor, such as a velocity sensor or an acceleration sensor, known in the art.
  • the sensors typically generate an electrical or optical signal that is related to the parameter being measured by the sensors.
  • the electrical or optical signals are conducted along electrical conductors or optical fibers carried by the streamer to a recording system.
  • the recording system is typically disposed on the vessel, but may be disposed elsewhere.
  • a seismic energy source is actuated at selected times, and a record, with respect to time, of the signals detected by the one or more sensors is made in the recording system.
  • the recorded signals are later used for interpretation to infer structure of, fluid content of, or composition of rock formations in the earth's subsurface. Structure, fluid content and mineral composition are typically inferred from characteristics of seismic energy that is reflected from subsurface acoustic impedance boundaries.
  • One important aspect of interpretation is identifying those portions of the recorded signals that represent reflected seismic energy and those portions which represent noise.
  • Electromagnetic sources and receivers include electric sources and receivers (often grounded electrodes or dipoles) and magnetic sources and receivers (often wire multi-loop).
  • the electric and magnetic receivers can include multi-component receivers to detect horizontal and vertical electric signal components and horizontal and vertical magnetic signal components.
  • the sources and receivers are towed through the water, possibly along with other equipment, while in other surveys the receivers may be positioned on the ocean bottom.
  • Marine growth is often pictured in terms of barnacles, but also includes the growth of mussels, oysters, algae, bacteria, tubeworms, slime, and other marine organisms.
  • Marine growth results in lost production time required to clean the geophysical equipment.
  • marine growth speeds corrosion, requiring quicker replacement of equipment, and increases drag resistance, leading to increased fuel costs.
  • the elimination, or the reduction, of marine growth will have a major beneficial effect on the cost of marine geophysical surveying.
  • marine growth presents a significant problem for a geophysical vessel operation due to downtime caused by a need for its removal, equipment damage, reduced seismic data quality due to increased noise, increased fuel consumption, and exposure of the crew to dangers associated with a streamer cleaning operations.
  • the invention is a marine sensor cable.
  • the marine sensor cable comprises a jacket covering an exterior of the streamer, wherein the jacket comprises an outer portion containing biocide disposed in a co-extrusion process.
  • the invention is a method for producing a marine sensor cable jacket with anti-fouling properties.
  • the method comprises providing a co-extruder to construct a polyurethane jacket for a sensor cable with a first extruder constructing an inner portion of the jacket and a second extruder constructing an outer portion of the jacket; producing a mixture of thermo polyurethane and biocide; supplying thermo polyurethane to the first extruder; supplying the mixture of thermo polyurethane and biocide to the second extruder; and constructing the polyurethane jacket with the outer portion containing the biocide.
  • FIG. 1 shows typical marine data acquisition using a sensor cable according to one example of the invention
  • FIG. 2 shows a cut away view of one embodiment of a sensor cable segment according to the invention
  • FIG. 3 shows a sensor cable jacket with an outer portion containing biocide that can be used in some examples.
  • FIG. 4 is a flowchart showing an embodiment of the method of the invention for producing a marine sensor cable jacket with anti-fouling properties.
  • Marine growth is a problem for anything that is submerged in or moves through sea water for significant periods of time, including marine geophysical equipment.
  • biocide properties biocide properties
  • copper has anti-fouling properties against marine growth when submerged in sea water.
  • the invention is a system and a method for protecting marine geophysical equipment from marine growth.
  • the following discussion of the invention will be illustrated in terms of surface jackets of sensor cables, but this is not a limitation of the invention.
  • Any form of geophysical equipment that can be and is disposed in a body of water, is vulnerable to marine growth, and has a polyurethane-based outer covering is considered appropriate for application of the present invention.
  • the invention can be applied to lead-ins covered with polyurethane-based materials.
  • any form of geophysical equipment that can be and is disposed in a body of water, is used in electromagnetic (including natural source magnetotelluric) prospecting, and has a polyurethane-based outer covering, is also appropriate for application of the present invention.
  • the invention can be applied to sensor cables carrying electromagnetic receivers.
  • the invention is a system and method for application of a coating comprising a biocide to surfaces of geophysical equipment components covered by polyurethane-based materials.
  • the biocide coating will greatly reduce or perhaps even eliminate problems associated with marine growth.
  • One embodiment of the invention is applicable to manufacturing surface jackets for sensor cables.
  • This embodiment is a co-extrusion process in which biocide is mixed into an outer layer of the surface jacket. This method ensures long anti-fouling effectiveness, since as the biocide residing in the outer layer erodes along with the wear-and-tear of the polyurethane base material, new biocide become exposed and effective.
  • the biocide comprises particles of copper or particles of an alloy containing a significant amount of copper.
  • Copper alloys include, but are not limited to, brass, copper oxide, copper thiocyanate, copper bronze, copper napthenate, copper resinate, copper nickel, and copper sulfide.
  • FIG. 1 shows an example marine seismic data acquisition system as it is typically used for acquiring seismic data.
  • the invention is not limited to towed seismic streamers, which are only employed here for illustrative purposes.
  • a seismic vessel 14 moves along the surface of a body of water 12 such as a lake or the ocean.
  • the marine seismic survey is intended to detect and record seismic signals related to structure and composition of various subsurface earth formations 21 , 23 below the water bottom 20 .
  • the seismic vessel 14 includes source actuation, data recording and navigation equipment, shown generally at 16 , referred to for convenience as a “recording system”.
  • the seismic vessel 14 or a different vessel (not shown), can tow one or more seismic energy sources 18 , or arrays of such sources in the water 12 .
  • the seismic vessel 14 or a different vessel tows at least one seismic sensor cable 10 near the surface of the water 12 .
  • the sensor cable 10 is coupled to the vessel 14 by a lead-in cable 26 .
  • a plurality of sensor elements 24 or arrays of such sensor elements, are disposed at spaced apart locations along the sensor cable 10 .
  • the sensor elements 24 are formed by mounting a seismic sensor inside a sensor spacer.
  • certain equipment in the recording system 16 causes the source 18 to actuate at selected times.
  • the source 18 produces seismic energy 19 that emanates generally outwardly from the source 18 .
  • the energy 19 travels downwardly, through the water 12 , and passes, at least in part, through the water bottom 20 into the formations 21 , 23 below.
  • Seismic energy 19 is at least partially reflected from one or more acoustic impedance boundaries 22 below the water bottom 20 , and travels upwardly whereupon it may be detected by the sensors in each sensor element 24 .
  • Structure of the formations 21 , 23 can be inferred by travel time of the energy 19 and by characteristics of the detected energy such as its amplitude and phase.
  • FIG. 2 is a cut away view of a portion (segment) 10 A of a typical marine seismic sensor cable ( 10 in FIG. 1 ).
  • a sensor cable as shown in FIG. 1 may extend behind the seismic vessel ( 14 in FIG. 1 ) for several kilometers, and is typically made from a plurality of sensor cable segments 10 A as shown in FIG. 2 connected end to end behind the vessel ( 14 in FIG. 1 ).
  • the sensor cable segment 10 A in the present embodiment may be about 75 meters overall length.
  • a sensor cable such as shown at 10 in FIG. 1 thus may be formed by connecting a selected number of such segments 10 A end to end.
  • the segment 10 A includes a jacket 30 , which in the present embodiment can be made from 3.5 mm thick polyurethane and has a nominal external diameter of about 62 millimeters.
  • the jacket 30 will be explained in more detail below with reference to FIG. 3 .
  • each axial end of the jacket 30 may be terminated by a coupling/termination plate 36 .
  • the coupling/termination block 36 may include ribs or similar elements 36 A on an external surface of the coupling/termination plate 36 that is inserted into the end of the jacket 30 , so as to seal against the inner surface of the jacket 30 and to grip the coupling/termination plate 36 to the jacket 30 when the jacket 30 is secured by and external clamp (not shown).
  • two strength members 42 are coupled to the interior of each coupling/termination plate 36 and extend the length of the segment 10 A.
  • the strength members 42 may be made from a fiber rope made from a fiber sold under the trademark VECTRAN, which is a registered trademark of Hoechst Celanese Corp., New York, N.Y.
  • the strength members 42 transmit axial load along the length of the segment 10 A.
  • the mating coupling/termination plates 36 are coupled together using any suitable connector, so that the axial force is transmitted through the coupling/termination blocks 36 from the strength members 42 in one segment 10 A to the strength member in the adjoining segment.
  • the segment 10 A can include a selected number of buoyancy spacers 32 disposed in the jacket 30 and coupled to the strength members 42 at spaced apart locations along their length.
  • the buoyancy spacers 32 may be made, for example, from foamed polyurethane or other suitable material.
  • the buoyancy spacers 32 have a density selected to provide the segment 10 A with a selected overall density, preferably approximately the same overall density as the water ( 12 in FIG. 1 ), so that the sensor cable ( 10 in FIG. 1 ) will be substantially neutrally buoyant in the water ( 12 in FIG. 1 ).
  • the buoyancy spacers 32 provide the segment 10 A with an overall density very slightly less than that of fresh water.
  • the segment 10 A includes a generally centrally located conductor cable 40 which can include a plurality of insulated electrical conductors (not shown separately), and may include one or more optical fibers (not shown).
  • the cable 40 conducts electrical and/or optical signals from the sensors (not shown) to the recording system ( 16 in FIG. 1 ).
  • the cable 40 may in some implementations also carry electrical power to various signal processing circuits (not shown separately) disposed in one or more segments 10 A, or disposed elsewhere along the sensor cable ( 10 in FIG. 1 ).
  • the length of the conductor cable 40 within a cable segment 10 A is generally longer than the axial length of the segment 10 A under the largest expected axial stress on the segment 10 A, so that the electrical conductors and optical fibers in the cable 40 will not experience any substantial axial stress when the sensor cable 10 is towed through the water by a vessel.
  • the conductors and optical fibers may be terminated in a connector 38 disposed in each coupling/termination plate 36 so that when the segments 10 A are connected end to end, corresponding electrical and/or optical connections may be made between the electrical conductors and optical fibers in the conductor cable 40 in adjoining segments 10 A.
  • Sensors which in the present example may be hydrophones, can be disposed inside sensor spacers, shown in FIG. 2 generally at 34 .
  • the hydrophones in the present embodiment can be of a type known to those of ordinary skill in the art, including but not limited to those sold under model number T-2BX by Teledyne Geophysical Instruments, Houston, Tex.
  • each segment 10 A may include 96 such hydrophones, disposed in arrays of sixteen individual hydrophones connected in electrical series. In a particular implementation of the invention, there are thus six such arrays, spaced apart from each other at about 12.5 meters.
  • the spacing between individual hydrophones in each array should be selected so that the axial span of the array is at most equal to about one half the wavelength of the highest frequency seismic energy intended to be detected by the sensor cable ( 10 in FIG. 1 ). It should be clearly understood that the types of sensors used, the electrical and/or optical connections used, the number of such sensors, and the spacing between such sensors are only used to illustrate one particular embodiment of the invention, and are not intended to limit the scope of this invention. In other embodiments, the sensors may be particle motion sensors such as geophones or accelerometers.
  • a compass bird 44 may be affixed to the outer surface of the jacket 30 .
  • the compass bird 44 includes a directional sensor (not shown separately) for determining the geographic orientation of the segment 10 A at the location of the compass bird 44 .
  • the compass bird 44 may include an electromagnetic signal transducer 44 A for communicating signals to a corresponding transducer 44 B inside the jacket 30 for communication along the conductor cable 40 to the recording system ( 16 in FIG. 1 ). Measurements of direction are used, as is known in the art, to infer the position of the various sensors in the segment 10 A, and thus along the entire length of the sensor cable ( 10 in FIG. 1 ).
  • a compass bird will be affixed to the sensor cable ( 10 in FIG. 1 ) about every 300 meters (every four segments 10 A).
  • the interior space of the jacket 30 may be filled with a gel-like material 46 such as a curable, synthetic urethane-based polymer.
  • the gel-like material 46 serves to exclude fluid (water) from the interior of the jacket 30 , to electrically insulate the various components inside the jacket 30 , to add buoyancy to a sensor cable section and to transmit seismic energy freely through the jacket 30 to the sensors 34 .
  • the jacket 30 may include an outer portion 52 and a remaining inner portion 50 .
  • the jacket 30 may be made from polyurethane, including both portions 50 , 52 .
  • Sensor cable jackets made of polyurethane are well-known in the art.
  • the outer portion 52 is also polyurethane, in which biocide is mixed at a desired ratio of biocide to thermal polyurethane to create the protective outer portion 52 of the sensor cable jacket 30 .
  • Thermal polyurethane is a raw grain-like material that is fed into an extruder to manufacture a tubular polyurethane sensor cable jacket.
  • the biocide is copper or copper alloy particles and the desired ratio comprises 10% to 40% copper or copper alloy in the mixture of copper or copper alloy with thermo polyurethane.
  • One example of a method for producing such a jacket with the biocide, such as copper or copper alloy particles, disposed in an outer portion 52 of the jacket 30 is co-extrusion.
  • Extrusion is typically a process in which thermoplastic material is fed into a barrel and moved along by a rotating screw towards a die. The material is gradually melted as it moves down the barrel, either from friction or heaters. The melted material is forced through the die into a desired shape and then cooled.
  • Co-extrusion is the process of extruding multiple layers of material simultaneously. Co-extrusion extrudes two or more materials through a single die from separate extruders arranged so that the extruded materials merge and weld together into a laminar structure before cooling.
  • This co-extrusion process produces a continuous polyurethane jacket 30 , without layers, but with the biocide embedded in the outer portion 52 of the jacket 30 .
  • the outer portion 52 comprises approximately 10% of a thickness of the jacket 30 . This method ensures long anti-fouling effectiveness, since as the biocide residing in the outer portion 52 erodes along with the wear-and-tear of the polyurethane base material, new biocide become exposed and effective.
  • the biocide comprises a combination of copper or copper alloy particles and other biocide materials.
  • FIG. 4 is a flowchart showing an embodiment of the method of the invention for producing a marine sensor cable jacket with anti-fouling properties.
  • the invention is here illustrated with the embodiment utilizing copper or copper alloy particles as the biocide. This is not intended to limit the invention, in which other materials that have biocide qualities can be employed or included with the copper or copper alloys.
  • a co-extruder is provided to construct a polyurethane jacket for a sensor cable with a first extruder constructing an inner portion of the jacket and a second extruder constructing an outer portion of the jacket.
  • thermo polyurethane and copper or copper alloy particles is produced in a desired ratio.
  • the desired ratio comprises 10% to 40% copper or copper alloy.
  • thermo polyurethane is supplied to the first extruder of the co-extruder in block 60 .
  • the mixture of thermo polyurethane and copper or copper alloy particles from block 61 is supplied to the second extruder of the co-extruder in block 60 .
  • the co-extruder from block 60 constructs the polyurethane jacket with the outer portion containing the copper or copper alloy particles.
  • the outer portion comprises approximately 10% of a thickness of the jacket.
  • the biocide coating of the invention prevents settlement of the invertebrate larvae (macro-fouling), algae, and bacteria (micro-fouling) that cause marine growth.
  • depositing biocide onto sensor cable jackets will prevent or reduce invertebrate, algae, and bacteria settlement. Reduction of marine growth on sensor cable jackets will result in several advantages, including the following.
  • the reduction of marine growth will reduce eddy formation at the surfaces of the sensor cable jackets, bringing about a consequent reduction of noise caused by the turbulent flow.
  • the quieter towing will improve the signal-to-noise ratio, a great benefit in geophysical surveying.
  • the reduction of marine growth will reduce drag on a towed streamer, allowing the equipment to be towed through the water with higher energy efficiency.
  • This higher efficiency could produce a reduction in fuel costs for the same survey configuration.
  • the higher efficiency could allow greater towing capacity (such as an increase in the number of streamers, the length of each streamer, or the towing spread) at the current fuel costs and towing power of the seismic vessel.
  • the reduction of marine growth will reduce production time lost to cleaning or replacing sensor cable jackets. This will also reduce work boat and cleaning equipment exposure hours for the crew. The reduction of marine growth will reduce the wear and extend the operational life of the sensor cable jackets.
  • biocide density is adjusted to produce a protective coating that provides the advantages discussed above and, at the same time, is suitable for the seismic or electromagnetic cable application.
  • a copper or copper alloy coating should not be so thick or contain so much copper as to interfere with the acoustic properties of sensors in the streamers, such as hydrophones and geophones, or the properties of electromagnetic sensors.
